I really love the little Kreons that come within the Kre-o sets and I was wanting a Sunstreaker one to go with my Sideswipe. Rather than wait for Hasbro to possibly come out with one, I decided to make my own. I took two different Kreons, Sunstorm and Bumblebee, and a Robot Heroes Sunstreaker. I mixed pieces from the two Kreons together and sanded down Sunstorm's helm. I cut off the head fins from the RH Sunstreaker as well as the engine from his back (at least, I think that's an engine?). I glued those pieces onto the helm and the back of the figure and voila! Sunstreaker was born. I'm really happy with how he turned out (and yes, I know the yellows are different shades - I'm okay with this).
